For the following graph five countries with the highest TB incidence rates during 2024 were chosen. The graph presents the TB incidence rates over time in the selected five countries. Overall, TB incidence rates have been on a steady decline since 2000, however a slight increase in all 5 countries was observed during 2020. This rise during 2020 has concernigly continued in Kiribati, Papua New Guinea, Philippines and Timor-Leste.

This figure shows the TB incidence rates across continents during 2024. Africa has the highest median TB incidence rate at 139.5. Great variability is observed in Oceania, with the highest TB incidence rate being 945 and lowest being at 1.9.

The highest undernourishment prevalence is seen mainly in sub-Saharan Africa and South Asia. While the prevalence of undernourishment has decreased between 20001 and 2022 in many countries, some coutnries such as the Democratic Republic of Congo and Zimbabwe have unfortunately experienced an increased prevalence during recent years.

The following graph shows the ten countries with the highst undernourishemnt prevalence during 2022. Haiti had the highest prevalence at 50.4% of the population experiencing undernourishment.

For the following graph five countries with the highest undernourishment prevalence in 2022 were selected. The graph presents the undernourishment prevalence over time in the selected five countries. While undernourishment prevalence was declining in the 2000s, the prevalence of undernourishment is now on the rise in all five countries. The prevalence is now higher in 2022 compared to the 2001 prevalence in all five countries.

This figure shows the undernourishment prevalence across continents during 2022. The highest median undernourishment prevalence is seen in Africa at 16.9. Europe had the lowest undernourishment prevalence.

The following scatter plot shows the relationship between TB incidence and undernourishment over time globally. From 2001 to 2022, there is a general trend of decreasing TB incidence and undernourishment prevalence. There is a slight relationship between TB incidence and undernourishment. For example, Djibouti had the highest TB incdence rate in 2001 (2650), and amongst the highest undernourshment prevalence (41.9%). As the undernourishment prevalence dropped to 12.9% the TB incidence also dropped to 462. However, not all countries follow these trends. Kiribati and the Philippines which have the highest TB incidence rates in recent years have very low undernourishment prevalence.

This figure shows the undernourishment prevalence and TB incidence in 2022. Again there is a slight relationship seen between the two variables, which is more visible when looking at continents individually. The relationship between undernourishment and TB incidence is particularly strong in the African continent.
